Blinking cruise control light.
A blinking cruise control light is due to the fact that Subaru has built most of its cars to turn on the cruise control light whenever there is an issue with the power train system.
This prevents and stops you from using cruise control if there is a problem.
If you notice a catalytic converter code, then know that it could be due to a failure in the converter or there could be an issue with an oxygen sensor.
Majority of the time this happens due to the converter, but try also check the oxygen sensor readings first That could also be another cause for a blinking cruise control light
